Abstract
The Gas Research Institute (GRI) has been supporting a comprehensive research and development program on in-line inspection techniques for natural gas transmission pipelines. This program contains assessments of state-of-the-art nondestructive evaluation methods, improvements in current approaches, and developments of advanced inspection technologies. The elements of the GRI Nondestructive Evaluation Program range from laboratory evaluations of the capabilities of inspection technologies to large-scale measurements in simulated pipeline settings. Each level of research stresses a quantification of both the limits of detection and the accuracy of characterization of pipeline imperfections that are found by in- line inspection tools. The overall goal of GRI's Nondestructive Evaluation Program is to develop and improve technologies that will help gas pipeline companies maintain the physical integrity of their transmission systems, prevent pipeline shutdowns, and reduce maintenance costs. This paper summarizes the results of the GRI program to date in relationship to their direct application to in-line inspection of gas transmission pipelines. The program consists of three main elements: facilities development, research on current inspection technologies, and research on future inspection technologies. The facilities development is centered around the Pipeline Simulation Facility; the research on current inspection technologies is aimed at improving magnetic flux leakage analyses; and the research on future inspection technologies is centered on stress-corrosion crack detection and characterization.
